Random Loss of Power - AgentofChaos - 08-21-2025
I have a 2014 Freightliner 114SD and periodically while driving the truck just shuts off. No warning. We have checked all the grounds, replaced the kill switch, changed all the sensors on the intake and manifold, and changed the PNDB box. Anyone have a new idea?

Could be a malfunctioning Fuel Shutoff Valve.

Do all the lights (dash/headlights) go out too? Just the engine shuts off? No codes ?

Check the fuse panel in the engine compartment. There should be a fuse/relay box. Check the fuses and give the wires into the box and the fuses a good amount of tug and wiggle test. The ignition power feed runs through here. It also runs to the cpc in the cab located bottom center of cab by drivers right foot behind paneling. This has wires running from the ignition switch, also check ignition switch itself.
Check the power lockout switch also. Check the batteries and connections.
